/*
* Hacked in DIR_COLORS support for linux. ------------------------------
*/
/*
* If someone asked me, I'd extend dircolors, to provide more generic
* color support so that more programs could take advantage of it. This
* is really just hacked in support. The dircolors program should:
* 1) Put the valid terms in a environment var, like:
* COLOR_TERMS=linux:console:xterm:vt100...
* 2) Put the COLOR and OPTIONS directives in a env var too.
* 3) Have an option to dircolors to silently ignore directives that it
* doesn't understand (directives that other programs would
* understand).
* 4) Perhaps even make those unknown directives environment variables.
*
* The environment is the place for cryptic crap no one looks at, but
* programs. No one is going to care if it takes 30 variables to do
* something.
